Key Takeaways
-
A round or pointed round brush is best for fine lines and small numbered areas, while a flat or bright brush is best for covering large areas quickly.
-
A standard kit ships with three brushes in small, medium, and large sizes, which cover most of a canvas.
-
Brush sizes run on a 00 to 8 scale, and matching size to section size keeps lines clean.
-
Cleaning brushes after every session and reshaping bristles while wet keeps them usable for many more sessions.
-
A stiff, dried-out brush can often be revived with a warm water and mild soap soak instead of thrown out.
-
Synthetic bristles hold up better with acrylic paint than natural hair, which was built for oil paint.
A paintbrush looks simple until you start using one. Keep at it, and something changes. You notice how it drags across the canvas, how a slight tilt turns a thick line into a thin one, and before long it stops feeling like a tool. It starts feeling like part of your hand, especially a few paint by numbers canvases in.
Getting there starts with picking the right brush, and that's usually where people get stuck. Stand in front of a wall of brushes at the art store and everyone else seems to know something you don't. It just depends on one question, are you covering space fast, or handling something small and detailed?
Once you know the answer, the rest falls into place. Start with the four parts that make up a brush, then the eight shapes built from them, and picking the right one stops being a guess.

Frequently Asked Questions
Get to Know Your Paintbrush
A paint brush consists of four principal parts that each perform a particular function, which influences the way you paint.
-
Bristles: The bristles, also known as hairs, may be natural, synthetic, or a combination of both. They control how smoothly the paint spreads and how fine or bold your lines appear.
-
Ferrule: The ferrule is the metallic band that attaches the bristles to the handle and ensures that they stay firmly attached.
-
Crimp: This is where the ferrule is firmly screwed to the handle.
-
Handle: It is usually made of wood or acrylic, which influences the comfort and balance of the brush while painting.
Acrylic Paint Brushes
Your paint brush is your main tool for creating vibrant, detailed artwork. Each brush type serves a unique purpose, and using them correctly can improve your paintbrush drawing skills significantly.
1. Round Brush
Has a round or pointed tip.
Good for sketching, outlining, detailed work, controlled washes, and filling small areas. It can create both thin and thick lines, fine at the tip and wider as you apply more pressure. Best used with thinned paint rather than thick paint.
2. Pointed Round Brush
Slightly narrower than the standard round brush, featuring a sharply pointed tip.
Good for fine details, delicate lines, retouching, and small spot work.
3. Flat Brush
Features a square tip with medium to long bristles.
Good for bold strokes, broad washes, and filling large spaces. The edge can be used for clean lines, sharp edges, and stripes. Long-haired flat brushes are also ideal for applying varnish.
4. Bright Artist Paint Brush
Flat with slightly curved edges and shorter bristles.
Good for short, controlled strokes and for applying thick, heavy color. Works best for painting up close rather than from a distance.
5. Filbert Brush
Has a flat, oval-shaped tip with medium to long bristles.
Good for blending and creating soft, rounded edges, such as flower petals. This brush combines the benefits of both round, for detail, and flat, for coverage, brushes.
6. Fan Brush
Has flat, fanned-out bristles.
Natural bristles work well for smoothing, blending, and feathering, while synthetic ones are ideal for creating textures like clouds and leaves. When using acrylics, choose a sturdy fan brush to prevent the bristles from clumping together.
7. Angular Flat Brush
Features flat, angled bristles at the tip.
Good for curved strokes, filling corners, and reaching small areas with precision. It can also cover larger areas, similar to a flat brush.
8. Detail Round Brush
Round brush with shorter bristles and a shorter handle.
Good for intricate details and short, precise strokes. Despite its size, it holds more paint than you might expect. Reach for this one when a canvas is packed with fine linework and tiny numbered sections. It's the detail brush for paint by numbers work that rewards a steady hand.
Flat vs Round Brush
The flat vs round brush question actually has a pretty simple answer once you break it down. Round wins for outlines, small sections, and anything with a tapered line. For backgrounds, skies, and big blocks of a single color, flat is the way to go. Keep both within arm's reach, and you won't be digging through your kit mid-canvas trying to remember which one does what.
How to Choose the Right Brush Size
Selecting the right size makes your paintbrush stroke clean and even. A brush that is too large can blur or smudge details, while a brush that is too small may make filling large areas time-consuming and result in patchy coverage.
Brush sizes also run on their own numbered scale, usually from 00 to 8, and that number indicates how wide the tip is. Here's how to match paint by numbers brush sizes to whatever area you're covering.
Tips For Using Paint Brushes Effectively
Holding your brush correctly changes your painting. Even the best brushes will be useless when used in a bad way, and even the simplest habits can make a significant change in your outcomes.
-
Clean your brushes after every painting session. A quick rinse and gentle cleaning maintain the bristle shape and make your brushes last much longer.
-
Lightly dip the brush into the paint, and wipe off the excess to control paint flow. This prevents thick messy strokes and gives you more even results.
-
Build up your colors slowly. Apply in thin layers, not thick coats, to avoid streaking and to achieve a softer, more natural-looking color blend
-
Choose quality tools, because buying the best paint brushes makes a huge difference. They blend better, hold the paint evenly, and make the whole process of painting more fun.
Common Brush Mistakes Made by Beginners
Even experienced paint by numbers artists make simple mistakes that affect their artwork. Avoiding these can save you time and effort.
-
Too Much Water. Thins paint and dulls colors.
-
Dirty Brushes. Dried paint causes uneven strokes. Clean them after each use.
-
Pressing Too Hard. Bends bristles and leaves rough edges.
-
One Brush For All Areas. Use a small brush for details and a large one for backgrounds.
-
Low-Quality Brushes. They shed bristles and don't hold paint well, making strokes messy.
-
Skipping The Reshape. Let a brush dry with splayed bristles, and it holds that bent shape for good, so get in the habit of reshaping the tip every time you rinse.
How to Clean and Store Your Brushes
There's a real difference between knowing how to clean paint by numbers brushes properly and just rinsing them under the tap and hoping for the best. One gets you a brush that lasts a year; the other gets you a brush that's done after one project.
A handful of brush care tips cover most of it.
-
Right after you paint, not the next day: Use warm water and mild soap for acrylic paint brushes. Gently reshape bristles and avoid soaking overnight, since sitting in water for hours softens the glue in the ferrule.
-
Don't stop rinsing too soon: Keep working lukewarm water through the bristles until it runs clear, reshape the tip or edge while it's still damp, then lay the brush flat or hang it bristle side down to dry.
-
Give bristles somewhere to point up, not down: A jar or a brush organization rack keeps tips from bending against a drawer bottom, and a roll up brush case is worth it if you paint on the go, since it keeps everything separated and protected.
There's a side benefit too. Building steady control with a small brush carries over into other activities off the canvas. Occupational therapy programs, including work described by St. Jude Children's Research Hospital, use repetitive fine motor tasks a lot like detail brush work to help patients rebuild hand coordination and grip strength.
Do Paint By Numbers Kits Come with Brushes?
Yes, a standard paint by numbers kit from Canvas by Numbers comes with three brushes, small, medium, and large, plus the numbered canvas, premixed acrylic paints, a reference sheet, and an instructions manual.
Those three brushes do more work than you'd expect. Small handles the fiddly detail sections, medium takes care of most of the mid-sized areas, and large plows through backgrounds in a fraction of the time. Custom kits ship with that same three-brush set, too, whatever design you pick.
Better Brushes Make Better Paintings
Choosing the right paintbrush can completely change how you feel about paint by numbers. A good brush makes each stroke smoother, brings out fine details, and helps your artwork look cleaner.
High-quality brushes don't just save time; they also make painting more fun and less frustrating. Ready to put any of this to use? Pick and order something from the full kit collection, and give your brush skills a canvas worth framing.
FAQs
What brushes come with a paint by numbers kit?
Three brushes, small, medium, and large, come standard in every kit. Small tackles the detail work, medium covers most mid-sized sections, and large gets through backgrounds fast.
What brush sizes do I need for paint by numbers?
Sizes run on a scale from 00 up to 8. For most beginners, the three brushes already in the kit cover everything, fine detail, mid-sized sections, and big backgrounds alike.
Which brush is best for fine details?
Round and pointed brushes are ideal for fine lines, intricate areas, and retouching. A detail round brush or a pointed round brush has a point sharp enough to easily work in tiny numbered sections and for delicate touch-ups.
Should I buy my own brushes?
For most beginner projects, the three brushes already in the kit are usually enough. It starts to make sense to buy your own once you want finer control, paint often enough to wear brushes out, or just like having backups on hand. A small set of extra sizes also tends to hold up better across many canvases.
How do I clean and store my brushes?
Use warm water and mild soap for acrylic paint brushes. Gently reshape bristles and avoid soaking overnight. Store brushes bristle side up or flat rather than standing them tip down in a water jar, since standing them on their tip destroys the point over time.
Why are my brushstrokes showing?
Usually that means the paint is going on too thick or the brush is too dry to begin with. Try loading less paint, working in thin even layers, and smoothing each stroke in the same direction.
Flat vs round brush, which one for what?
Round is your go to for outlines, small sections, and anywhere you need a tapered line. Flat is faster for backgrounds, skies, and big blocks of a single color.
How do I keep bristles from splaying?
Pressure is usually the culprit, so easing up while you paint helps a lot. Get in the habit of reshaping the tip every time you rinse and never let a wet brush stand on its bristles in a water jar.
Synthetic vs natural bristles, which is better?
Synthetic bristles are durable and suited for acrylics, holding shape longer over repeated painting sessions. Natural bristles are softer and work well with oils but wear faster with acrylic paints. For most paint by numbers work, synthetic is the safer choice, and the one most kits ship with anyway.
How do I revive a stiff or dried-out brush?
Give it a soak in warm water with a bit of mild soap or brush cleaner for about fifteen to twenty minutes. Work the bristles gently with your fingers to loosen whatever's dried in there, then rinse and reshape while it's still damp.
